Acquisition of Mechanical Testing Instrumentation in Support of Research on the Electrical Geophysical Properties of Soils

Abstract

The major goal of this project was to acquire key instrumentation to enhance basic earth materials and processes research on the relationships between the electrical and mechanical properties of sediments being performed under ARO Research and Education Program (REP) project W911NF-18-1-0442. The acquired instrumentation was selected to significantly expanded the capabilities of the Near Surface Geophysics (NSG)research laboratory at Rutgers University Newark (RUN) to include soil strength/failure testing according to ASTM standards. The instrumentation (that could not be included in the REP proposal due to budgetary limitations) would dramatically enhance the quality of the ARO-funded research performed at RUN by allowing direct measurements of soil strength/failure parameters for correlation against electrical geophysical signals. The goal of the research conducted with these instruments was to generate new information on the sensitivity of advanced, broadband, low frequency complex electrical measurements to soil compression and failure. The basic research conducted with this instrumentation will ultimately contribute to efforts at remote assessment of soil geotechnical properties. The specific aim of the instrumentation purchase was to permit high quality, automated measurements of strain and strength/failure parameters on a wide range of unconsolidated sediments of relevance to ARO. The goal was to acquire instrumentation that is expandable, allowing the in-situ measurements of complex electrical properties during uni-axial and triaxial strength testing.
